Here is the list of 100+ databases I made during my life. I made them public for everyone, from students practicing data analysis, to multi-national companies in real estate and automobile industry.

Most projects I made from personal interest to distribute freely or sell for professional use. Some projects I made at request and published on website to allow other customers to purchase if interested.

I offer web scraping services in VB.NET and Python, making custom databases according your requirements. I work in Word and Excel, other file formats available: CSV, SQL, XML, JSON.

HDB Database is an original compilation “Made by Teoalida” which took over 500 hours of work. Collecting data from multiple sources, I manually entered data in one Excel table for all HDB blocks ever built in Singapore, indicating block number, street address, postal code, GPS coordinates, construction year, lease commence date, number of floors, number of units breakdown by flat type, upgrading programmes, brochures and floor plans.

The database has been purchased by several companies, including home insurance, telecommunication, door-to-door services, real estate portals, flyer distributors, as well as many people who did not told me what business field they are in.

If you need to download a list of condos in Excel format to organize your work, I made some databases for you, extracting data from SingaporeExpats and PropertyGuru, plus the database of MCST Enquiry from BCA for people doing phone SMS marketing to condo management corporations. Sorry for people looking for email marketing but I do NOT have MCST email addresses.

If you want to download a database of mobile phones specifications in Excel format to create a website, use in a GSM shop or anything similar, I created an Excel database for you, including smartphones, old featured phones, tablets and smartwatches. I offer FREE monthly updates and weekly updates for $100/year.

Worldwide cities database organized by country, state and province, with city population indicated. This is a handmade database that I started in 2003, currently having over 8000+ cities, with possibility of expansion in the future, based on demand from customers.

I offer data mining and web scraping services. “Scraping” usually means coding a bot that visit a list of given pages, copy specific data from each page and put it in an Excel / CSV file automatically, at rate of few pages per second. Watch the video!

If you are building a website, a mobile app, or just require specific data but cannot find in usable format, just give me link to a website having required data, I will make a scraper and turn website into an Excel database, for you and for future customers.

Are you looking for a database of planets and satellites in Excel format with their facts and figures, for research or to make a website? I made a database in 2014 with planets and main satellites, sourcing data from solarsystem.nasa.gov.

Given by high number of free downloads, in 2019 I made a larger Excel database containing EVERY celestial body listed on NASA website (1 sun, 8 planets, 5 dwarf planets, 190 satellites) and offer for paid download.

Are you looking for a database of countries in Excel format with their facts and figures, for research or to create a website? I made a database for you. Took few hours to make a scraping script which extract data from The World Factbook and create a CSV file. Takes about 35 min to extract the 268 entries, and I can update anytime you want!

After making databases of HDB and condos from Singapore, as well as public and private housing estates from Hong Kong, and other databases, in November 2015 I started making a database of skyscrapers, published it in January 2016, having over 15,000 buildings taller than 100 meters. Under construction buildings are included.

First time I used Excel to organize and rate songs I had in my computer was in 2002. The current Music Database, including complete discographies of selected artists, is a project started in 2005, shortly after connecting to internet I started creating a database in Excel with the MP3 songs downloaded from internet, to review each song and give a rating from 0 to 16, and make top best artists, best albums, best genres, etc, using complex mathematical formulas, to show to friends exactly what music I like and how much. Database is useful for me to organize my own music. How useful is for other people, I don’t know… your feedback is needed to make a better database for YOU and future customers!

Homeowners associations does have phone numbers of some owners (is a good practice to give your contact info to be announced in case there is a problem in your home while you are away), car insurance companies also have phone numbers of their clients, but what makes you to think that they would give their database to you or potential competitors? Also, distributing / selling phone numbers without owner consent is ILLEGAL all over the world. In Singapore you can be fined up to $10,000 or up to 12 months of jail according pdpc.gov.sg.

As graphic designer and enthusiast in computer history, I became curious how the monitor dimensions evolved over the years and analyzed which screen resolutions were most popular, so I created these Excel files:

On 1 April 2009, HDB improved its Resale Flat Prices e-service, now showing transactions for last 1 year instead of last 3 months, also added flat model beside floor area. I copied the listings for 1 year (April 2008 – March 2009) in Microsoft Excel, which were displaying 20 per page. I spent about 10 days at 5 hours per day. I did this for purpose of personal analysis, for example estimate average apartment size nationwide and per town, and showing the results of analysis in HDB Statistics page. Few months later HDB showed all transactions in a scroll-able list rather than 20 pages, allowing me to copy transactions much faster, so started to update my database once per year.

Are you looking for a database of airports and other airfields in Excel format for research or to make a website? I made a database for you, you can open XLS file, save as CSV and import in SQL if needed.

Are you a car parts shop, car rental, dealership, tuning, insurance company, or any other business that deal with cars? Or you just need a table with cars sold in Singapore in Excel format to make a website, a mobile app, or data analysis for a school project?

I spent several hours coding a scraper for sgcarmart.com and created this Excel database for YOU!

Since I made in 2016 a very complete and accurate Mobile Phones Database, several people asked me if I can make a database of laptops or computers.

This is a trouble: while phones have under case same specifications, and we have websites like gsmarena.com which shows all phone models from most popular manufacturers from 1994 to present, laptop manufacturers produce them with a lot of different specifications under same case, and allow you to further customize them before ordering. Laptops can also be customized aftermarket by anyone. So, any laptops database I make, its accuracy risk to be poor (not match the specifications of laptops available for sale on various websites).

On 27 September 2018 an Indian visited www.teoalida.com/database/cities and asked me if I have database of HOTELS… not sure what made him to ask about hotels in a page about city population. He needed only 5 columns: hotel name, address, city, country, star rating. His budget was very low so we could not make the deal. But making a world hotels database is a GREAT IDEA because it may be in the interest for many people all over the world, not like Car Database, which require dozens separate databases for each region.
